The K2 Cortex 125 Zonal BOA is a compact performance boot for expert women who want precision and power in a snug, low-volume fit.
The boot has a flex 125 and a low-volume width of 98 mm via MultiFit for a close, direct fit. Closure comes from a Zonal BOA Fit System, where micro-adjustable dials and low-friction lace guides spread the closure evenly and in zones across the foot, backed up by a 45 mm elasticated cam strap for dynamic power transfer. Shell and cuff are TPU with a rugged TPU coating on the top and bottom for durability and weather resistance, and both are fully heat-moldable. The EliteFit Pro liner has precision-mapped support zones and thermoformable foam for a supportive, personal fit. The GripWalk outsoles are pre-installed and replaceable, and the boot can also run an ISO 5355-certified alpine outsole. The Fastfit instep eases entry and exit.
